Later this year will mark the 10 years since “Lost” premiered on ABC.

To celebrate, executive producers Damon Lindelof and Carlton Cuse along with seven cast members reunited over the weekend at PaleyFest, the annual two-week event in LA consisting of television show panels for fans.

Among the cool trivia bits we learned, it turns out the writers also disliked random background characters Nikki and Paulo, Daniel Dae Kim (who played Jin) wasn’t speaking (real) Korean for a while on the show, and Yunjin Kim’s (Sun) role was written just for the actress.

THEN: Daniel Dae Kim played Korean-speaking Jin-Soo Kwon.

NOW: Kim is the star of CBS' "Hawaii Five-0" remake.

THEN: Yunjin Kim played Jin's wife, Sun.

NOW: She stars on ABC series "Mistresses."

Kim also starred in three South Korean films with the latest called "The Neighbors."

THEN: Henry Ian Cusick played time-traveling Desmond.
